Newbie Question: How to capture motion_notify_event in tables?
Hi, I'm trying to write a gui with a ruler, grid lines, and some widgets. So my approach was to create a table and attach a ruler on it. For the grid lines, I used gdk to draw segments on the table. My problem now is that I can't seems to capture the motion_notify_event in the table in order for the ruler indicator to move, and I can't use a drawing area widget because its not a container. So can anybody suggest how to do this? Thanks. -- Alfredo P. Ricafort [EMAIL PROTECTED] ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

Drag and drop files
Hi, Using GTK2+. I have thought of making drag and drop of files from/to an application I make, to/from e.g. Netscape Messenger to make/get an e-mail attachment. I've looked at gtk_drag_xxx, but I haven't been able to find out how I can drag/drop files. Do anyone have experience with this? I would be glad to get a pointer in the right direction and of course a code-example would be great.

Re: Row height in treeview
Nope, it's just a function of whatever's in the row. Extra whitespace should be the same as for GtkLabel and whatever else, it's making room for possible descenders from p and y and g for example, and on top for capital letters. You could shrink the font in your gtkrc. My font size is smaller than the default icon size in a treeview/list. SPECS font=Tahoma; 8pt; custom-ft2-bytecode-enabled; RH8/ The icons are 22x22, but even when there aren't any icons in a treeview/list it still takes as much space as with those icons in it. Is it possible to make those icons 16x16 instead of 22x22? - Rich _ STOP MORE SPAM with the new MSN 8 and get 2 months FREE* http://join.msn.com/?page=features/junkmail ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list

Re: Get clicks OUTSIDE the window
Havoc Pennington wrote:
You have to gdk_grab_pointer() and gtk_grab_add() during the time that
the modal window is active.
I realized that (and the modal window too, or I couldn't gdk_grab
modalwin-window ... :-) ). The Gtk source was useful. But not
sufficient.
The situation is: I have a GtkEntry. When the user right-clicks it, the
modal window (containing two spinbuttons and two buttons) pops up over
it.
In the best case, the button_press_event for the entry stays active
for two clicks (the second when the popup is already displayed!), in the
worst case event handler for the popup window is never called (so I
have to switch to a terminal and kill the app).
In the Gtk sources (in gtkcombo.c) I saw a comment regarding not
explicitly grabbing button presses, but couldn't understand it...
The other strange thing is that when the cursor is over the spinbutton
entries, it changes (this means that spinbuttons are getting some
events, IIUC), but the buttons won't PRELIGHT when it's over them (so
they don't get some events, apparently).
I tried grabbing a lot of different events (button presses, mouse
movements, etc) - at most I got an X error saying invalid value when
using GDK_ALL_EVENTS_MASK .
The relevant code is:
static gboolean _popup_event(GtkWidget *widget, GdkEvent *event,
gpointer user_data)
{
gboolean rv=FALSE;
switch(event-type) {
case GDK_DESTROY:
gdk_pointer_ungrab(GDK_CURRENT_TIME);
gdk_keyboard_ungrab(GDK_CURRENT_TIME);
gtk_grab_remove(widget);
break;
case GDK_BUTTON_PRESS: {
// Close window if click is outside
GdkEventButton *e=(GdkEventButton*)event;
GtkRequisition req;
gtk_widget_size_request(widget, req);
if(0e-x || 0e-y || e-x req.width || e-y req.height) {
gtk_widget_destroy(widget);
rv=TRUE;
}
} break;
default:
break;
}
return rv;
}
static void gtk_widget_pop_on(GtkWidget *popup, GtkWidget *ref, gboolean
over,
gboolean exp_x, gboolean
exp_y)
{
gint x, y, maxx=gdk_screen_width(), maxy=gdk_screen_height(), w, h;
GtkRequisition req;
g_assert(popup!=NULL);
g_assert(ref!=NULL);
g_assert(GTK_IS_WINDOW(popup));
// avoid NULL==popup-window
if(!GTK_WIDGET_REALIZED(popup)) gtk_widget_realize(popup);
gdk_window_get_origin(ref-window, x, y);
if(!over) {
// Upper left corner just under 'ref' widget
gtk_widget_size_request(ref, req);
y+=req.height;
}
// Anyway, it must stay on screen
gtk_widget_size_request(popup, req);
w=req.width;
h=req.height;
x=MIN(x, MAX(0, maxx-w));
y=MIN(y, MAX(0, maxy-h));
gtk_widget_popup(popup, x, y);
if(exp_x)
w=maxx-x;
if(exp_y)
h=maxy-y;

if(event-button==3) {
gtk_widget_pop_on(create_date_edit(), widget, TRUE, FALSE, FALSE);
rv=TRUE;
}
return rv;
}
I tried propagating event-time, too, but it didn't work :-(
I bet it's something obvious, once understood...
Tks.

GTK+(Win32) default font
How does GTK+ (Win32) determine the font it should use for menus, buttons etc? Recently all my GTK+ programs have started using a small hard to read font, where they were before using a normal sized one, and I haven't been able to work out how to reset it.

gtk+ 2.2.0 configure
I am trying to configure the gtk+2.2.0 on rh linux 8. I did not have any trouble installing the dependent libraries. however, when configuring gtk with ./configure --prefix/opt/gtk it does good until it gets to a step creating m4macro. Then, it throws an error stating that it cannot find the input file m4marcros/Makefile.in. Any ideas? Greg ___ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
